A test set-up was developed in which the fresh mortar and concrete can be sheared in a pressure cell by a vane as a part of a concrete rheometer (ICAR). The concrete is directly loaded in the pressure cell by a hydraulic jack. Preliminary shear tests were conducted on concretes with ...
The flow test of concrete is not just a phrase; it’s a critical property that has a direct impact on the strength and overall quality of highly workable concrete. It’s like the secret ingredient in a recipe; a minor deviation in the water-to-cement ratio, ingredient proportioning, or a...
To optimize the strengthening method using the fiber reinforced polymer (FRP) for the reinforcement of the concrete structure with cracks, the three-point bending test was conducted on the concrete beams wrapped with different layers of FRP materials. The strain gauges were pasted on the surface ...

CD 02-028 COMPARISON OF DIFFERENT CURING EFFECTS ON CONCRETE STRENGTH The purpose of this investigation was to conduct a laboratory test program on how much different curing conditions affect the attainable strength of concrete. To achieve this purpose, a laboratory test program was conducted. The ...

Near-fault earthquake load causes more serious damage in reinforced concrete (RC) structures when compared with far-field earthquake load. Particularly, a short column under the near-fault earthquake load is vulnerable to shear failure, which requires sp
In Japan, the Nuclear Power Engineering Corporation (NUPEC), sponsored by the Ministry of Economy, Trade and Industry (METI), had conducted a series of seismic reliability proving tests using full-scale or close to full-scale models to simulate an actual important equipment that is critical for...
